Also you could try removing this file:
Documents\Electronic Arts\The Sims 3\ userPresets.package
Although I'm not sure that would cause this. It can make some pretty cool things happen though, such as making walls show up as floors and vice versa.

Caches are always the first thing to go. But I'll test with the thumbnails and the user presets.

So also when you save the game it compares the changes (and the CC reference from the world).

Well, exporting the wolrd without any cc, except for the patterns, made no difference. Still bleeding. Maybe it's the patterns, after all.

I'll do more testing tomorrow. It's half past one at night and I have headache.

Oh, it's Pralinesims. Thank you. I got it a long time ago along with a house but there was no indication of who had made it.

Okay, after testing and removing thumbnails, userPresets, all the cc, all the caw cc and pretty much everything except the patterns, the bleeding continued. Then finally I removed all the patterns except the one by Pralinesims. This time there were no bleeding and the missing textures showed up as blue, which is normal when there's a texture missing. So I think it's safe to say that the problem is caused by one or all my own patterns together. At least I think that if it was caused by something else, then bleeding should've happened with Pralinesims' pattern, as well. I truly hope I'm right. I'm going to get rid of them completely, make the few absolutely necessary ones straight into walls and floors cc. Now I just have to go through all the affected lots in EIG and pray that it will save without crashing. Let's see how that goes...

Hi, guys. I just uploaded the test version of my world and wanted to thank you all for your help. I wish I could give you all a huge pile of cookies but all I can say is thank you. And Norn , thanks for not letting me give up because at one point I was seriously considering it.
